FATMAP difficulty grade
When you go down the Kandahar slope, after the first flat part you get to a path to go to a steeper part.
This gets you into the valley to the way down to the Cabane des Bois.
Before this valley starts you can see Mont Tubang on your left.
To access to this run you need to traverse all the way above this mountain.
You keep on going until you find cliffs just in front of you.
Here you just need to go down diagonally to the right.
There are a few rocks to avoid in the middle, and you need to be careful if you follow straight down instead of going to the right because there are cliffs at the beginning.
